Dinner Bill Contribution

A group of friends decided to go out for dinner together. The total bill came to $120, and they agreed to split the bill evenly.

Four of the friends are paying with cash, and the fifth friend, Alicia, has offered to pay $20 more than her share to cover her friends' portions.

Calculate the amount that each friend who is paying with cash will pay after Alicia covers the additional amount. Provide your answer as a decimal or as a fraction.
